Good Day,

Just finishing up my 7SS build and I’m getting ready for some load development. Anyone have any load recommendations for H4831SC with Berger 180 Hybrid? Can’t find any H1000 or RL26 so I’d like to find a good substitute load if I can. Thanks.

Not too much help since I used a different bullet, but I used 61 grains of H4831sc under a 169 Hammer Hunter. I bet you could start around 55 grains of H4831sc and work up to pressure. A call to Rich would be helpful.

I shoot the 180 hybrid in my 7 Max, a bit more capacity but close. Really like RL-23. My accuracy node is at 3,025 fps. Off hand, jump is .060-.065
